Thanks Ruben. Unfortunately it didn’t work. All drivers are fine except Realtek I2S audio driver, which I actually need… It says ‘the driver is not intended for this platform’.
But I’ve just found the soultion. I’ve read somewhere, that downloading audio driver from lenovo atom tablets, fix the problem. And it really did! I’ve used driver from lenovo Miix 310-10ICR and my sound is back!
